During the ongoing BMO Capital Markets Digital Entertainment Conference in New York, COO of interactive entertainment business Dennis Durkin stated the Xbox 360 version of Call of Duty: Modern Warfare 2 has doubled up the PlayStation 3.

"Initial feedback from retailers is that Call of Duty: Modern Warfare 2 [on Xbox 360] has outsold the PS3 2:1," he said.

Durkin also stated this past Tuesday was the largest day on Xbox Live ever, with over two million concurrent players on at a given time. He also touted the service by taking a jab at Sony, saying Xbox Live had no server issues even with such a large number.
